FRANK G. STIMSON, OF HAMLDEN, CONNECTICUT, ASSIGNOR TO WINCHESTER REPEAT- CONNECTICUT, A CORPQRATION OF CON- ANTIROLLING HAN'DLAMIP.

Application filed May 20, 1922.

To all whom it may concern:

Be it known that I, FRANK Ur. S'rIMsoN, a citizen of the United States, residing at No. 1148 Whitney Avenue, Hamden, in the county of New Haven, State of Connecticut, have invented certain new and useful Improvements in Antirolling Handlamps; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the same.

The present invention relates to battery hand lamps of the type wherein an electric battery operates in conjunction with a small incandescent lamp bulb and a reflector to project a beam of light through a lens.

It is an object of the present invention to provide a tubular hand lamp with a head of such cross section that the hand lamp will not readily roll when laid down on a sloping surface.

In the preferred embodiment illustrated in the drawing, the flaring, sheet metal head is of polygonal cross section, but witha cylindrical front edge to which the usual lens supporting ring may be threaded.

Further objects and advantages will become clear from the following detailed description, taken in conjunction with the accoInpanying drawings, wherein,

Fig. 1 is a side elevation of the complete hand lamp;

Fig. 2 is an end elevation of the same.

Fig. 3 is a section of the flaring head on the line 3-3 of Fig. 2 and Fig.4 is a similar section on the line M.

Fig. 5 shows the invention applied to a tubular hand lamp in which the battery cas ing consists for the most part of a fiber tube.

Referring to Figs. lto 4 inclusive, the metal casing 1 wherein the batteries are housed is provided with the usual bottom cap 2 threaded thereto, and a sliding thumb piece 3, it is threaded at its front end to engage with the threaded cylindrical portion 4 of an outwardly flaring sheet metal head 5.

This head has at its front edge a cylindrical portion 6 (Fig. 3), with threads pressed therein, for engagement with the threads 7 of a ring or collar 8 of usual construction,

shown in the drawing The has a plane front face.

sheet metal head 5 is .pressed or' Serial No. 562,319.

shaped by usual metal working operations to form a lura-lity of facets 10, eight in number, and each presenting a substantially plane surface of about the outline indicated in Figs. 3 and 4:. This gives to the periphery of the flaring head an octagonal outline, as indicated in Fig. 2, with the corners of the octagon projecting far enough to serve as anti-rolling shoulders when the hand lamp is laid down on a fiat surface, as indicated diagrammatically in Fig. 1.

buch a. hand lamp is ornamental in appearance, is light in weight, has its Weight well distributed, is economical to manufacture and offers no impediment to the ready attachment of the lens supporting ring or collar.

In the embodiment illustrated in Fig. 5, the tubular casing 11 is of fiber with threaded collars 12 and 13 riveted thereto. Collar 12 is threaded to receive a bottom cap 14 and collar 13 is threaded to receive the cylindrical portion of the flaring sheet metal head 15. The latter may be the same in details of construction as the head shown in Figs. 3 and 4 and is threaded at its front edge to receive the knurled collar 16 whereby the convex lens 17 is sppported in front of the usual reflector and lamp bulb. Various changes in details of construction and in the form of the flaring head may be made without departing from the spirit of my invention as defined by the appended claims.

I claim j 1. A tubular hand lamp having a flaring sheet metal head with projecting shoulders and a threaded cylindrical front portion, and a lens-supporting collar threaded to said cylindrical portion, the diameter of said collar being such that said shoulders may impede the rolling of said hand lamp when laid on a plane surface.

2. In a battery hand lamp, the combination of a cylindrical casing having a threaded front end, a flaring sheet metal head threaded thereto, said head being shaped with facets to form a polygonal periphery, and having a cylindrical front edge threaded to receive a lens-supporting ring, said rin being of such diameter that the polygona portion of the head can serve as an antirolling device. I

In testimony whereof I aifix my si nature.

FRANK G. STI SON.
